The Angles of Armageddon: If multiple religions around the world from all times in history, describe similar beings with extraordinary powers coming down from the skies; if they took the time to record these as factual events and use these descriptions to start religions to lead their existences; isn’t it probable there’s more than some validity to their stories? If intelligent beings came down from the sky; and we know Aliens are real from our scientific exploration of the facts; isn’t it more reasonable to assume that the super intelligent beings that came down from the heavens, were in fact Aliens, and not “Gods”; physical extraterrestrial beings, possessing God like characteristics, in the eyes of primitive man?

So which scientific fact are you alluding to when you say "we know Aliens are real?"

Its a quote from a book named: "The Angels of Armageddon". The answer is far to complicated for me to answer. Theirs a number of pages dedicated to proving the phenomenon genuine, through: theoretical conclusions, historical documentations, eye-witness accounts, and traces of physical evidence. One such piece of evidence allegedly originated at the biggest crash sight of all time, "The Roswell Incident" belonging to a man named Dr. Roger Lier. Have you ever heard about his debris?
